Trait Implementations§

impl Collector for CountCollector

Source§

fn collect( &mut self, _doc_id: DocId, _score: Score, _positions: &[(u32, Vec<ScoredPosition>)], )

Called for each matching document positions: Vec of (field_id, scored_positions)
Source§

fn would_collect(&self, _doc_id: DocId, _score: Score) -> bool

Whether this score can enter the collector’s retained result set. Read more
Source§

fn collect_owned( &mut self, doc_id: DocId, score: Score, positions: MatchedPositions, )

Source§

fn needs_positions(&self) -> bool

Whether this collector needs position information
Source§

impl Default for CountCollector

Source§

fn default() -> CountCollector

Returns the “default value” for a type. Read more
